The Scala Workshop 2026

The Scala Workshop is the continuation of the Scala Symposium, providing a forum for researchers and practitioners to discuss the design, implementation, and applications of the Scala programming language. Topics include language features, compiler internals, type systems, libraries, tools, and industrial applications.

This year, the workshop follows a simplified format, focusing on talk proposals rather than full papers. The goal is to facilitate discussion and exchange of ideas without the overhead of formal publications. Talks can cover ongoing research, practical experience, or perspectives on Scala and its ecosystem.

Call for Presentations

The Scala Workshop 2026 invites talk proposals on all aspects of the Scala programming language, including but not limited to:

• Language design and implementation
• Type systems and functional/object-oriented programming paradigms
• Compiler development and optimizations
• Libraries, frameworks, and tooling
• Applications of Scala in industry and research
• Experience reports and case studies
• Performance, scalability, and concurrency
• Interoperability with other languages and ecosystems

Talks are expected to be approximately 20 minutes, including Q&A.

Submission Format

Submissions:

• must summarize the planned talk in at most 2 pages;
• must be typeset in LaTeX using the ACM template with the options \documentclass[sigplan,nonacm]{acmart};
• must be anonymous.

Submissions that do not follow these requirements will be desk-rejected.

Accepted talk proposals will be published as post-proceedings on the workshop website. Presenters may optionally include their slides.

Evaluation Criteria

Submissions will be evaluated according to the following criteria (not all need to be satisfied):

• Relevance: Alignment with topics of interest to the Scala community.
• Clarity: Quality of exposition and structure.
• Originality: Novelty of ideas, techniques, or applications.
• Discussion Potential: Ability to inspire engaging and productive discussions.
• Rigor: Technical accuracy and depth.

How to Submit

We will accept submissions through the workshop’s HotCRP instance from January 23 to March 23, AoE. The submission link will be announced on the workshop website.

For questions, contact the organizers at scala-workshop@epfl.ch.

Note that the submission site is not hosted on hotcrp.com and will require creating a new account.

Attendance

Talks must be presented in person in Brussels. Registration fees will be announced on the ECOOP website.

We look forward to your contributions!
